Kalle Lasn is the co-founder of the Adbusters Media Foundation, the organization responsible for launching Buy Nothing Day as a yearly, global event. He explains that while most participants used to see the day simply as an escape from the marketing mind games and frantic consumerism that have come to characterize modern life, the focus has since shifted in light of the new political mood surrounding climate change.

“So much emphasis,” he notes, “has been placed on buying carbon offsets and compact fluorescent lightbulbs and hybrid cars that we are losing sight of the core cause of our environmental problems: we consume far too much.”

“Buy Nothing Day isn't just about changing your routine for one day. It’s about starting a lasting lifestyle commitment. With over six billion people on the planet, it is the responsibility of the most affluent − the upper 20% that consumes 80% of the world’s resources − to set out on a new path.”

His book, "The Moneyless Man, a Year of Freeconomic Living is published this week (the proceeds will go to a charitable trust).
